WINDOW-FRAME FR FABRCF Specification of Letters Patent.

Application filed July 31, 1918. Serial No. 243,666.

To all whom t may concern:

Be it known that JOHN CLAYTON Backus, citizen of the United States,residing at Snicthport, in the county of Mc- Kean and State ofPennsylvania, have invented certain new and useful improvementsin'Window-Fraines for Fabrics, of which the following isa specification.

This 'invention relates to an improved window frame particularlydesigned for use in mounting windows upon automobile tops or curtainsbut which is, however, adapted :for general use in securing a pane ofwindow vglass upon iabrio.1

VThe invention has as its primary object to provide a frame which may bestamped complet@l from suitable sheet metal and will thus be capable ofproduction at minimum cost and wherein the frame. holding a window pane,may be quickly `and easily secured upon a' piecefotl fabric without theaid or" l separateutastening devices, to the end that the frame may beapplied with a minimum expenditureof time and labor. 25

A further object of the invention is to rovide a'i'rame wherein a watertight joint:

will be formed not onl between the fabric and the window pane. lint alsobetween the fabric and the coacting plates or' the trame for thuselectually excluding the weather at thewindow opening.

The invention has as a further object in this connection to provide aconstruction wherein the coacting plates of the frame will be clam-pecltogether' by suitable clamping means' carried by one ot' the saidVplates and wherein the stress of the said 'clamping 'means vwill bewholly distributed between the inner and outer edges of the plates tothus obtain' maximum clamping effect tending to orrnwater tight jointsbetween the window pane and the fabric as well as between the fabric andthe plates.

And the invention has as a further object to provide a constructionwherein the clamping means employed between the plates will act tocenter the window frame with respect to the window opening in thefabric.

Other and incidental objects will appear as the description proceeds.vIn the draw- -ings, wherein I have illustrated the preerred embodimentof the invention, and wherein similar reference characters designatecorresponding parts throughout the several views:

dow pane may be ot' glass or other suitable transparentmaterial, Incarrying the in*- vention into effect, I employ enacting clampl ing'members or plates A and B respectively,

the plate A forming the inner plate of the frame and the plate B theouter plate of the.

frame, Ifhvese plates may be of annular configuratlon' or other desiredshape, aecordlng to the character of window preferred, and

are preferably stamped from suitable 'resilient sheet metal. inthedrawings, the curtain is illustrated as being provided with circularwindow opening and the kframe is accordingly also shown as beingcircular yto surround this opening, the inner diameter et elf-.rh of theplates being substantially equal eo that of thesaid opening.

Substantially midway between its side4 edges, the plate A is bent toprovide a continuous rib. 13. From this rib the inner margin ofv theplate is bent to form an outwardly bowed pane engaging flange 14 havinga gripping race l5 at its outer edge. From the rib 13 the outer marginofthe plate bent outwardly to define a channel 16 and from this channelis continued to provide an inwardly directed fabric gripping flange 17disposed at an acute angle to the plane ot the gripping face 15 of theflange 14 of the said plate. Struck from the outer margin of the 'plateat suitable spaced pointsthereon, is a series of gripping I tongues 18extending from the crown of the gin of vthe plate is bent to provide anoutwardly bowed pane engaging flange 20 formed at its outer edge with agripping B is ofslightlyl less width than l midway vao face 21 adaptedto'register with the 'gripping face 15 of the iiange 14e ofthe plate A.From the, shoulder 19, the innermargin of the plate B is bent to providean out wardly bowed fabric gripping flange 22 adapted to fit within thechannel 16 of the plate A .to coact with the flange 17 of this latterplate. .Formed inthe plate 18 o the plate A is a series of spacedopenings 23 disposedadjacent the base of the shoulder 19 of th'esaidplate..l It is now to be. observed that the platesA and B, as thusdescribed are of such-construction that each of the said plates may bestruck ata single operation from a piece'of suitable sheet metal so thatthe frame may accordingly be produced at minimum. cost.

In applying the frame, the4 plate A islirst placed against the innerside of the curtain with the central opening vthrough the plateregistering with'the window opening 12in the curtain., the tongues 1.8beingsinit/ially straight so that these tongues may thus'` be forcedthrough the fabric of the curtain for centering'the'plate with'respectto the win-l dow opening in he curtain. The pane'll is then positionedagainst the ange 14; of the plate beneath rounding the window opening`therein so that, as particularly shown in ig. 2 ofthe drawings, thevcurtain will overlie the vpane upon its outer side. The plate B islthenpositioned over the plate A in mating relaf tion thereto, receiving theclamping tongues 18 through its openings 23. The flange 20v 0f theplate' B will thus overlie the margin of the curtain surrounding thewindow opening -12 therein while the lange 2 2 of the said plate will bereceived. within the channell of the plate A bearing over the curtain.

Thus, the""'iiange 17 of the plate A wl coact with theiiange 22of-`,the-plate B Ifor centering this latter plate upon the plate A sothat illustrated in the the center opening through the plate B willregister with theJ center'opening in the plate A while the gripping face21 of the flange 20 of the plate B will be disposed to contact ythe'curtain vsurrounding with the margin ofy the window openingv 12immediately at the periphery of .ther

said opening. Having initially positioned-the plate B upon the plate A,the free extremities of the tongues 18 are then bentv outwardly anddownwardly against the flange 22 of the-latter plate, as drawings, fortightly clamping the plates together.

`Attention is now directed to the fact that when the plates A and B areclamped to gether, the curtain'will be wedged between the grippingflanges 17 and 22 of the plates at the outer edges of the plates sothatawatertight joint will be formed between the fabric of the curtain andthe plates. Furi thermore, it will be seen that since the flange 15 of te flange 111 of 'flange 22 of the plate Consequently, B at suitableJointsthereon'for receiving the tongues the margin of the curtain sur--17 ris above the plane of the gripping face theplate A, this flange isadapted to support the outer edge of the B to fulcruin thereon in aplane substantially midway between the gripping 'faces 15 and 21 of theplates, since the flanges 14 and 20 of the plates are outwardly bowed toextend-in spaced relation to the periphery of the 1pane 11 ateach sidethereof, the plates will, when the tongues 1S are tightened to clamp theplates together, tend to rock upon each other -atftheir outer edgesandaccordingly swing.

lthe gripping faces l151 and-210i? the anges 414 and 20 into bindingcontact .one with the inner side ofthe pane :and the curtain at theotherwith the outer side of the pane. The pane will accordingly beyieldably gripped between plates to provide a watertight joint] betweenthe pane and the fabric of the curtain.A The weather at thel window oening in the. curtain will thus beeffectual thermore, I

in this connection, itis to be notedy that since the plates A and B ofthe frame I their' inner are formed to clamp the pane at edges, only bythe gripping faces 15 and 21', and are. also formed to clamp the fabriconly at their extreme outer edges, all of the clamping stress exerted bythe tongues 18 applied with a minimum expenditure of upon the fabric lthe flanges Hand 20 of the I dily' Y labor and time. Furthermore, thenecessity for the use of'separate fastenin mounting the frame upon thefa nated. l
